  • Miracle worker
Size: 33.8 Fl Oz (Pack of 1)
My hair has been breaking off and falling out for years. I finally started using this conditioner to see if it would help. I immediately saw a difference in texture. So I also got the shampoo. I now have minimal breakage and fall out since using this product. My hair has also been growing. I have started using more redkin products to continue to help with my hair. ... show more

  • Best shampoo for thin/
Size: 10.1 Fl Oz (Pack of 1)
The media could not be loaded. I have very thin and fine hair. My hair can barley go a day after a wash without getting greasy. This shampoo and conditioner literally saved my hair. Definitely the best smelling one redken has. My hair feels great, healthy, and full. Also it’s the longest lasting shampoo and conditioner I have that I can go without washing it! So buyyy ... show more

  • So Thankful that this product ACTUALLY WORKS!
Size: 10.1 Fl Oz (Pack of 1)
I have experienced a noticeable change in hair shedding and loss since purchasing the entire system via Amazon. My hair used to cover my shower and clog the drain AND still comb out a clumps with little breakages and shedding every time I styled. I am used to having thick hair and so this was the norm for me - about 1 1/2 cups worth hair loss at hair wash time. Since using Redken hair system, barely 1/4 cups worth or tablespoon worth of hair loss even when combing my hair post shower. I am a new regular consumer of this hair system. I am so thankful for this product. I am actually outgrowing my hair extensions lol and I want LONGER ones, now that my hair is actually growing past my shoulders - when from two pack of hair extensions to 1pack just to supplement my unevenness from when my ponytail was breaking my hair in a specific area. That area has grown about 4 inches but hasn’t caught up to the rest of my head yet. 🙌🏽✨🥰 Also, my previous shampoo and conditioners are Paul Mitchell - Awapuhi. So it’s not the price that matters, it’s what is IN this hair care system. I was hesitant because of the price and the amount of product. I wash my hair about once per week. Hair has grown approximately 2-4 inches and noticeable in a month the difference. I hope this review helps and makes sense - I rarely leave reviews, but I am so happy with this product, that I made the time! Picture is for reference of the smaller amount of hair loss. ... show more

  • Strengthens and leaves hair soft
Size: 10.1 Fl Oz (Pack of 1)
I loved this conditioner. It leaves the hair soft, easy to detangle, and with less breakage when combing. The scent is light and pleasant. It is a bit pricey for the size, but it’s worth it for the results.

  • Smells phenomenal and hairs soft after use
Size: 10.1 Fl Oz (Pack of 1)
Works really well, hairs soft after use but after a day or two hair becomes dry and somewhat brittle, at least for me. Hair looks amazing the day you use it and smells phenomenal. Giving it more time and definitely will post results after a few more months

  • Buy it! You need this set!
Size: 10.1 Fl Oz (Pack of 1)
Coming here to say- BUY IT! I originally purchased this set for the growth factor. But If you are looking to TRULY get rid of the Frizz- this shampoo & conditioner will do it. I noticed a difference after the first wash!! While in the shower. Before I dried my hair I forgot to put heat protectant on it and my hair still was not frizzy after blow drying!!!! My hair feels amazing. Soft- yet luscious. The areas were breakage would stick out and not lay flat, now sits softly flowing with the rest of my hair- instead of frizzing and sticking out. I’m shocked how my hair looks and feels after the first wash and condition. I will never use another shampoo and conditioner again. Worth the price tag 1000% Will update on growth in a few months. ... show more

  • Works but you will have hair loss
Size: 10.1 Fl Oz (Pack of 1)
I bought both the shampoo and conditioner in the beginning November . It smelled really good and my hair felt so nice for the first 2 months , 3rd month in I started to notice growth , A little dry to my scalp and hair but smooth . I used these once/twice a week so I wasn’t over doing it . End of 3rd month and 4 month in i started noting hair loss more and more after each use that I ended up not finishing the bottle. Smell was good but it a drying shampoo to my scalp and hair and it did grow my hair 2-3 inches in 4 months but I experienced some hair loss . Maybe only use this a couple times a month or maybe it’s just not made for my hair type (2b hair ) . ... show more
